21 RSA_sign_ASN1_OCTET_STRING() signs the octet string B<m> of size
22 B<m_len> using the private key B<rsa> represented in DER using PKCS #1
23 padding. It stores the signature in B<sigret> and the signature size
24 in B<siglen>. B<sigret> must point to B<RSA_size(rsa)> bytes of
29 The random number generator must be seeded prior to calling RSA_sign_ASN1_OCTET_STRING().
31 RSA_verify_ASN1_OCTET_STRING() verifies that the signature B<sigbuf>
32 of size B<siglen> is the DER representation of a given octet string
33 B<m> of size B<m_len>. B<dummy> is ignored. B<rsa> is the signer's
38 RSA_sign_ASN1_OCTET_STRING() returns 1 on success, 0 otherwise.
39 RSA_verify_ASN1_OCTET_STRING() returns 1 on successful verification, 0
